1. A buoyant wave energy converter, comprising:
an upper chamber having a first fluid reservoir and a first gas pocket;
a lower chamber having a second fluid reservoir and a second gas pocket; and
an injection tube between and fluidly coupled to the upper chamber and the lower chamber, the injection tube to impel a fluid from the second fluid reservoir into the first fluid reservoir when the upper chamber, the lower chamber and the injection tube oscillate about a waterline with the upper chamber adjacent to the waterline and the lower chamber submerged below the waterline.
 
15. A method of converting wave energy, the method comprising:
capturing energy from waves of a body of water with a buoyant wave energy converter, the buoyant wave energy converter comprising an upper chamber having a first fluid reservoir and a first gas pocket, a lower chamber having a second fluid reservoir and a second gas pocket, and an injection tube between and fluidly coupled to the upper chamber and the lower chamber, the injection tube to impel a fluid from the second fluid reservoir into the first fluid reservoir when the upper chamber, the lower chamber and the injection tube oscillate about a waterline with the upper chamber adjacent to the waterline and the lower chamber submerged below the waterline; and
using the captured energy to power a computing system coupled to the buoyant wave energy converter.
